摘要:

在这篇评论中,我们提出了一个进展报告之间的联系,长持续时间的伽玛射线暴(GRB)和伴随的超新星(SNe)。分析是从观察者的角度出发的,重点放在观察和观察的建模如何限制我们对GRB-SNe的了解。我们讨论了它们的光度和光谱特性,它们作为宇宙学探测器的作用,包括它们测量的光度$-$下降关系,以及它们如何被用来测量哈勃常数。我们对它们的热测量特性进行了统计分析,并使用它来确定“平均”GRB-SNe的特性:其具有$E_{\rm K} \approx 2.5\times10^{52}$ erg的动能、$M_{\rm ej} \approx 6$ M $_{\odot}$的喷出物质量、$M_{\rm Ni} \approx 0.4$ M $_{\odot}$的镍质量、$v_{\rm ph} \approx 21,000$ km s $^{-1}$的峰值光球速度、$L_{\rm p} \approx 1\times10^{43}$ erg s $^{-1}$的峰值测热光度,并且在$t_{\rm p} \approx 13$天内达到峰值辐射热光。我们讨论它们的几何形状,考虑各种物理过程,被认为是权力的GRB-SNe的光度,以及是否存在差异GRB-SNe和SNe与超长持续时间GRB。我们讨论了GRB-SNe环境的观测如何进一步限制其祖星的物理性质,并概述了其疑似中央发动机的当前理论范式。我们还提出了一个概述的放射性供电的瞬变,已光度与短持续时间的伽玛射线暴。最后,我们通过讨论需要进行哪些额外的研究来进一步了解GRB-SNe,特别是二进制形成通道的作用以及GRB-SNe与超发光SNe的联系来结束综述。

英文摘要:

In this review we present a progress report of the connection between long-duration gamma-ray bursts (GRBs) and their accompanying supernovae (SNe). The analysis is from the point of view of an observer, with much of the emphasis placed on how observations, and the modelling of observations, have constrained what we known about GRB-SNe. We discuss their photometric and spectroscopic properties, their role as cosmological probes, including their measured luminosity$-$decline relationships, and how they can be used to measure the Hubble constant. We present a statistical analysis of their bolometric properties, and use this to determine the properties of the "average" GRB-SNe: which has a kinetic energy of $E_{\rm K} \approx 2.5\times10^{52}$ erg, an ejecta mass of $M_{\rm ej} \approx 6$ M$_{\odot}$, a nickel mass of $M_{\rm Ni} \approx 0.4$ M$_{\odot}$, a peak photospheric velocity of $v_{\rm ph} \approx 21,000$ km s$^{-1}$, a peak bolometric luminosity of $L_{\rm p} \approx 1\times10^{43}$ erg s$^{-1}$, and it reaches peak bolometric light in $t_{\rm p} \approx 13$ days. We discuss their geometry, consider the various physical processes that are thought to power the luminosity of GRB-SNe, and whether differences exist between GRB-SNe and the SNe associated with ultra-long duration GRBs. We discuss how observations of the environments of GRB-SNe further constrain the physical properties of their progenitor stars, and give an overview of the current theoretical paradigms of their suspected central engines. We also present an overview of the radioactively powered transients that have been photometrically associated with short-duration GRBs. We conclude the review by discussing what additional research is needed to further our understanding of GRB-SNe, in particular the role of binary-formation channels and the connection of GRB-SNe with superluminous SNe (abridged).
